A sensitive chemical test for the participation of oxirens in the decomposition of diazo-ketones has been developed, based on the subsequent rearrangement of oxocarbenes to αβ-unsaturated ketones. In this way oxiren participation has been demonstrated in the thermal and photochemical decomposition of a variety of diazo-ketones, including 3-diazoheptan-4-one, 1-diazo-3-phenylpropan-2-one, and 2,2-d
基于氧卡宾随后重排为αβ-不饱和酮的方法,已经开发了一种敏感的化学测试,用于检测环氧乙烷是否参与重氮酮的分解。以此方式,在多种重氮酮的热和光化学分解中,证明了奥西林的参与,包括3-重氮庚烷-4-酮,1-重氮-3-苯基丙烷-2-酮和2,2-二甲基-酮。 4-重氮己基-3-一。相反,在重氮酮与氧化银或氧化铜的催化分解中,没有环氧乙烷参与。还讨论了竞争过程(例如Wolff重排)的重要性。
